lb all whoma't may concern:

Be it hnown that we, GEORGE E. KELLER and Jnssn F. Pennini, citizens of the United States, residing at Vancouver, county of Clark, State ot' Washington, have jointly invented certain new and useful Improvements in Separators, of which the following is a specification.

ur invention relates to separators in general, and particularly to that class oi separators known as hydraulic, and used especially in mining to separate various grades ot ore.

The objects of our invention are to produce a device of eXtreme simplicity; to produce a device of minimum weight for the use of prospectors; and to produce a device of economical construction and use.

We accomplish the above objects, and other desirable results, by means of the construction illustrated in the accompanying drawing, like characters of reference indieating like parts throughout the several views, and in which:

liigure 1 is an axial sectional elevation oi our device.

Fig. 2 is a detail fragmentary view ol a. portion ot the ore iced pipe.

he device is inclosed by an outer casing 3, preferably made of glass, and having' at the lower end thereof a. head oi inverted truncated conical shape, and at the upper end thereof a head 5, substantially disk shaped.

The casing is clamped between said heads by bolt rods 6, and a water tight joint is ed'ected between the casing and the heads by gaskets 7 of rubber or other suitable material.

'lihe lower head 4 is provided with a cleanout cap 8 and a drain pipe 9.

lhegs 10 attached to head 4 support the device.

Centrally attached to head 5 is an inner casing 11, made preferably of glass, and having upon the lower end thereof an annu.- lar flange 12.

Said casing 11 is clamped between head 5 and flange 12 by bolt rods 18, and a water tight joint is eiiected between casing 11 and head 5 bv means of a gasket 14 of rubber or other suitable material.

Centrally mounted upon head 5, and above the same, is a pipe 15, having an outlet pipe 16 attached thereto, said pipe 15 be- .ing in communication with casing 11.

Water supplj7 pipes 17 enter` the head 5 in the annular space intermediate the casingg` and the casingll.

An ore supply pipe 12 is` disposed within pipe 15 and casing 11, the upper end thereot being connected to a suitable funnel 19, or the like, which closes the upper end of pipe 15.

lThe water introduced through pipes 17 Hows downward intermediate casings 3 and 11, upward through casing 11 and pipe 15. and is discharged from pipe 16, as illustrated by the full line arrows.

lThe ore, or other material to be separated, is introduced into casing 11 by means of pipe 18 and funnel 19, and there encounters the rising current of water within casing; 11.

rlhe intensity oi3 the upward current within casing' 11 is regulated so that it is just suiiicient to float the lighter particles of the material being,1 separated, but will allow the heavier particles to settle against the current into head 1.

ln order to facilitate the separation oi the particles under the action of the water current we find it desirable to discharge the material from pipe 18 in an annular ring of radially projected jets.

his we accomplish by terminating the pipe 18 some distance above the lower end ot casing 11, and suspending therefrom a pipe 20 by means oi straps 21.

The upper end of pipe 2O adjacent pipe 18 is closed, as shown in Fig. 2, and spaces 22 are lett between adjacent straps 21.

'lhe material to be separated is discharged from said spaces in substantially a radial manner, and subjected to the action oi the ascending; current ot water, which carries upward the lighter particles as shown by the full line arrows, and allows the heavier particles to sink into head ll as shown by the dotted arrows, whence 'they may be withdrawn by removing the clean-out cap 8.

Our invention may be made of any size and constructed of any material deemed convenient and suitable for a device of this character, and while we have illustrated and described a form ot construction and arrangement oi parts found desirable in matcrializiint,r our invern;ion,l we wish te include Bil in this` application for Letters Patent all mechanical equivalents and substitutes that may fairly be considered to come within the scope and purview of our invention-as defined in the appended claim.

Having disclosed our invention sol that others skilled in the art may be enabled to construct and to use the same what we claim as new and desire to secure by Letters Patent is: l Y

A separator comprising a reservoir; a

" downwardly projecting conical head upon the lower end of said reservoir; a head upon the upper end. of said reservoir; a tube secured to saidv head and projecting downward therefrom within-said reservoir and substantially coaxial therewith; a pipe se- ,Copies of this patent may be obtained for cured to said head and projecting upward therefrom and being` in connection with said tube; an overflow from said pipe; a feed pipe within said pipe and projecting downward within said'tube substantially coaxial therewith and havingadjacent the lower end' thereof a plurality of discharge slots; a feed hopper closing the upper end of said pipe and connecting with said feed pipe; and supply pipes entering said reservoir through said upper head thereof.

In witness Whereofwe claim the above as our own we hereunto set our hands, at

Portland, county of Multnomah, State of Oregon, this 3d day of April, 1917.
